UBUNTU-CVE-2021-4095

A NULL pointer dereference was found in the Linux kernel's KVM when dirty ring logging is enabled without an active vCPU context. An unprivileged local attacker on the host may use this flaw to cause a kernel oops condition and thus a denial of service by issuing a KVMXENHVMSETATTR ioctl. This fl...

kernel: dereferencing NULL payload with nonzero length

A flaw was found in the implementation of associative arrays where the addkey systemcall and KEYCTLUPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer...

DEBIAN-CVE-2017-1000255

On Linux running on PowerPC hardware Power8 or later a user process can craft a signal frame and then do a sigreturn so that the kernel will take an exception interrupt, and use the r1 value from the signal frame as the kernel stack pointer. As part of the exception entry the content of the signa...
